Ron Stone f125a8b892 Remove spurious escapes (r8,dsR8) 
This change addresses a long-standing issue in rST documentation imported from XML.
That import process added backslash escapes in front of various characters. The three
most common being '(', ')', and '_'.
These instances are removed.

SNMP Overview

provides a containerized solution using Net-SNMP, supporting both SNMPv2c and SNMPv3.

can generate SNMP traps for Alarm Events and Customer Log Events.

also supports SNMP GETs and WALKs of an Active Alarm table and a historical Event (alarm SET/CLEAR and log) table.

SNMP functionality is integrated into as an optionally configurable system application.

About SNMP Support

Support for Simple Network Management Protocol (SNMP) is implemented as follows:

  • available using the controller's node floating OAM IP address, over the standard SNMP UDP port 161, by default

  • SNMPv2c and SNMPv3 are supported versions

  • read-only access for all SNMP communities or all SNMPv3 users

  • supported SNMP operations are GET, GETNEXT, GETBULK, SNMPv2C-TRAP2, SNMPv3-TRAP

    Note

    SNMPv3 INFORM, and SNMP SET operations are not supported.

  • the SNMPv3 security levels that are supported are: NoAuthNoPriv, authNoPriv, authPriv

  • support for MD5 for auth, and DES for priv, see http://www.net-snmp.org/

For information on enabling SNMP support, see Enabling SNMP Support <enabling-snmp-support>.

SNMPv2-MIB (RFC 3418)

Support for the basic standard MIB for SNMP entities is limited to the System and SNMP groups, as follows:

Wind River Enterprise MIBs

Note

There are no product specific MIBs for wrsEnterpriseReg.mib and it will be supported in a future release.

supports the Wind River Enterprise Registration and Alarm MIBs.

Enterprise Registration MIB, wrsEnterpriseReg.mib

Defines the Wind River Systems (WRS) hierarchy underneath the iso(1).org(3).dod(6).internet(1).private(4).enterprise(1). This hierarchy is administered as follows:

  • .wrs(731), the IANA-registered enterprise code for Wind River Systems
  • .wrs(731).wrsCommon(1).wrs<Module>(1-...), defined in wrsCommon<Module>.mib.
  • .wrs(731).wrsProduct(2-...), defined in wrs<Product>.mib.
Alarm MIB, wrsAlarmMib.mib

Defines the common TRAP and ALARM MIBs for products. The definition includes textual conventions, an active alarm table, a historical alarm table, a customer log table, and traps.

Textual Conventions

Semantic statements used to simplify definitions in the active alarm table and traps components of the MIB.

Tables

See SNMP Event Table <snmp-event-table> for detailed descriptions.

Traps

See Traps <traps> for detailed descriptions.
